The Sakonnet River Bridge is a four-lane bridge spanning the Sakonnet River in eastern Rhode Island. The bridge carries RI 24 and RI 138 between the communities of Portsmouth and Tiverton, Rhode Island. The truss bridge was built in 1956 but closed and replaced in September 2012 with a box girder bridge. The replacement of the Sakonnet Bridge ended a several years long ban of heavy commercial vehicles weighing over 18 tons. Currently, there is intense debate among the Portsmouth and Tiverton communities over Rhode Island legislation authorizing tolls on the new box girder bridge.

The Sakonnet River Bridge (truss) opened in 1956 as a replacement for the Stone Bridge, about 0.8 mi (1.3 km) to the south. It became part of RI 24 during the 1960s after the completion of the Portsmouth and Tiverton Expressways. At one point, it was briefly considered for inclusion as part of the never-built Interstate 895. Upon completion of the new Sakonnet River Bridge (box girder bridge) in September 2012, the old truss bridge was closed.

Bicycles were not permitted on the old bridge, but will soon be allowed on the new bridge. [1]

Toll collection on this bridge started on August 19, 2013. After a lengthy legal battle, the toll was set at 10 cents per crossing. Toll collection was electronic only. Since there was no official plan on how tolls were to be collected from Non-EZPass users, the state had asked those travelers to pay using the honor system.[2]

By the late 1990s, the Sakonnet River Bridge's design had become obsolete, and transportation planners began to develop a plan for the bridge's future. Significant deterioration of the bridge necessitated a ban of vehicles weighing over 18 tons, re-routing traffic over the narrower and less commercial truck-friendly RI 136/114 and the Mount Hope Bridge[4] In 2003, the Rhode Island Department of Transportation (RIDOT) announced plans for a $120 million (USD) replacement bridge to be built just south of the existing bridge. Groundbreaking for the new bridge took place in April 2009, and the bridge opened behind schedule in September 2012. RIDOT expects to advertise for the demolition of the old truss bridge in 2014.
